• wherein the device body includes a striker housing part to detachably hold the striker, and an engaging protrusion located in the striker housing part and configured to engage with the locking pawl of the striker,
• the distal end portion of the striker is formed with separated right and left insertion leg portions located on a center side and operating portions located on right and left outer sides of the insertion leg portions, the operating portions including the locking pawls,
• the striker housing part includes a housing chamber formed with a guide rib for guiding the insertion leg portions in the front-back direction and engaging protrusions configured to engage with the locking pawls of the striker,
• the engaging protrusions are formed separately on an upper inner wall and a lower inner wall of the housing chamber, and
• when the distal end portion of the striker is inserted into the housing chamber, the operating portions of the striker pass between the separated upper and lower engaging protrusions while being pressed and deformed by the engaging protrusions, and the locking pawls engage with the engaging protrusions when the distal end portion of the striker is completely inserted in the housing chamber.
